tranny tranfer case?

[Pigeaten]

this tranny and transfer case came in 69 I just picked up, can anyone tell me what they are(for chevy?)

You can't KILL an NP 205 no matter how much you try

 

[Pigeaten]

could that go with with a 4L60e tranny?

 

[bobm]

@Lil'John would know better than me , but I believe so

 

[Pigeaten]

There is a saying that with enough time, money, or expertise(pick two) anything is possible.

From what I recall, the difference between a 4l60e and turbo 350 at the adapter is the 4l60 uses an o-ring while the turbo 350 uses a gasket. I believe Advanced makes an adapter to fix that issue.

Thanks,just bought a 5.3 from BD turnkey, guess I will get with George at Valley Hybrids to get his 2 cents

I'd be shocked if Georg recommended you run an NP205. Big, heavy, and crappy low range(2.0) with no option for lower. While bullet proof, so is an LC split case or a host of others.

Georg had no issue recommending a split case behind: 6.0L with NV4500, turbo 5.3L with 4l80 & doubler, AND 472 big block cady with SM465. Fairly stout case, relatively light weight, and 2.3 low range along with a 4.0 option.

Thanks for your knowledge , will let you know what he(I) decide

I am about to mate a NP205 to a 4L60e. Havent started yet so I dont have any wisdom for you. There is a 3:1 gear set yo can get for the 205.

I would say the split case is not an option if he already has center rear drive shaft. I would assume the rear axle is not toyota anymore.

On the split case, the axle being centered will have no bearing in a super long wheel base like an FJ55

Can you elaborate?

Sure. U-joints don't care where the angle is coming from; vertical or horizontal make no difference. They have a maximum operating angle.

Yeah I’m probably over thinking it a bit because it just seems wrong.

I’ve see two plane angle driveshaft’s on PTO’s but both ends are fixed and they operate at fairly low RPM’s so I’ve never really given them much thought.

In my mind getting the compound angles to both be 3° maximum that U-joints want to operate in on a leaf spring rear end through its operating range would be a monumental task. I know it’s fairly common on rock crawlers but they typically have reasonably low driveshaft RPM’s and we’re talking about FJ55’s and in reality they wouldn’t have an unreasonably high shaft RPM either so that angle of misalignment is probably higher into the 6° range or better.

Thanks for taking the time to reply.
